Abstract
The Wissenschaftslehre 1804-ii does not end with absolute knowledge in the 25th lecture, because this absolute knowledge is as sealed off from the common knowledge as the Absolute itself in the 15th lecture was. As matters stand in the 25th lecture the Wissenschaftslehre can neither meet its own claim to unify all knowledge in one system nor can the genesis of the absolute knowledge, which had to begin with common knowledge, be understood by means of the Wissenschaftslehre itself. The problem in linking absolute knowledge and common knowledge is that, on the one hand, absolute knowledge is hermetically closed. Therefore, nothing and especially not common knowledge can derive or result from it. On the other hand, absolute knowledge is not supposed to depend on anything but the Absolute itself. Therefore, it cannot be understood adequately as a condition for common knowledge. Fichte’s solution to this problem is to differentiate between the genesis of absolute knowledge and absolute knowledge itself. Common knowledge is necessary only for the genesis of absolute knowledge. However, the validity of the common knowledge depends on the pursuit of the absolute knowledge.
